Insights

Tumor necrosis factor (TNF) superfamily ligands are key therapeutic targets. This review reveals that TNF receptors form ordered hexagonal lattices for precise signaling, crucial for developing new cancer and autoimmunity treatments.

Area of Science:

  • Molecular Biology and Immunology
  • Structural Biology
  • Biophysics

Background:

  • Tumor necrosis factor (TNF) superfamily ligands regulate critical cellular processes including apoptosis, survival, and proliferation.
  • These ligands are significant therapeutic targets for cancer and autoimmune diseases due to their diverse biological functions.
  • Understanding the structure-function relationship of TNF receptor superfamily signaling is essential for targeted therapy development.

Purpose of the Study:

  • To review the latest literature on TNF receptor superfamily signaling, emphasizing structure-function relationships.
  • To propose a unified model for TNF receptor activation based on ordered surface arrangements.
  • To provide insights for designing improved therapies for cancer and immune-mediated diseases.

Main Methods:

  • Literature review of TNF receptor superfamily signaling.
  • Application of combinatorial principles to analyze receptor-ligand interactions.
  • Analysis of structural data suggesting ordered receptor arrangements on the cell surface.

Main Results:

  • Receptors must form highly ordered arrangements on the cell surface for activation by membrane-bound ligands.
  • Evidence suggests TNF receptors form antiparallel dimers that cluster into hexagonal lattices.
  • This hexagonal geometry positions activated receptors optimally for downstream signaling, irrespective of receptor type.

Conclusions:

  • A unified model of TNF receptor signaling is proposed, based on ordered hexagonal lattice formation.
  • This structural arrangement is critical for efficient signal transduction.
  • The findings offer valuable insights for the rational design of novel therapeutics targeting TNF receptor pathways in cancer and autoimmune disorders.

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
